ELECTRIC LIGHTING DEVICE.

SPECIFICATION forming part of Letters IIPatent No. 625,786, dated May 30, 1899. Application filed February 28, 1898. Serial No. 671,968. (No model.)

To aZZ whom it may concern:

Be it known that I, SAMUEL EARL MosHER, of Ohillicothe, in the county of Ross and State of Ohio, have invented certain new and useful Improvements in Electric Lighting Devices; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part of this specification.

My invention relates to improvements in electric lighting devices, and pertains to a device adapted to light at the top or within the top of a chimney.

The object of my invention is to provide an electric lighting device especially adapted for use in connection with the incandescent gas-burners such as the Welsbach, Niagara, Apollo, and others, the device being constructed and arranged to move over, within, and without the upper end of the chimney and producing a spark at the top or within the top of the chimney for lighting the burner.

In the accompanying drawings, Figure 1 is a perspective view of my invention shown attached to an incandescent gas-burner and in position for operation. Fig. 2 is an enlarged side elevation of the sparking devices looking from one side thereof, and Fig. 3 is a similar View looking from the opposite side thereof. Fig. 4 is a detached view of the pulley .or sheave which carries one of the sparking-arms. Fig. 5 is a view of the arm which carries the other sparking members. Fig. 6 is a sectional view taken longitudinal the spindle or shaft of the sparking members, showing the parts in position thereon.

A indicates an incandescent gas-burner to which my invention is applied.

B is a horizontal arm constructed to be attached to the lower portion of the burner, as illustrated, and is here shown of ahollow form and adapted to receive the lower laterally-bent end D of a standard E. The arm 13 may be constructed to be horizontally adjusted, if desired, and the standard E, projecting upward parallel the chimney of the burner,may also be longitudinally adjustable for the purpose of fitting the device to burners having chimneys of different types. The standard E, I preferably form of a tube,

through which the wire connections and the operating chain or cord, as hereinafter described, may pass, though the standard may.

its opposite end connected in any manner with the journal or shaft. Connected with this sheave is a curved sparking member or arm J, preferably formed of wire, and the said spiral spring normally holds the arm backward, as illustrated in solid lines in Fig. 1. Situated also upon this journal isa plate or arm K between the inner side of the sheave or pulley and the standard. A coiled spring L has one end connected with this plate and its opposite end connected with the sheave or pulley and the said spring normally holding the plate backward, as shown in solid lines in Fig. 1. This plate is provided with a socket M, carrying an insulating material N, and placed within this insulating materialN is a sparking member or arm P. It will thus be seen that two sparking members or arms are provided, and they are curved, as here shown, so that when they are thrown forward, as shown in dotted lines in Fig. 1, they 'will move within the upper end of the chimney, as shown. The spring connecting the plate and the sheave unites the sheave and the plate, as will be understood, and when the sheave is rotated to move its sparking member or arm within the chimney it carries with it the plate which has the other and coacting sparking member or arm. A cord, wire, or chain is connected with the tube, and when the standard E is of tubular form, as here shown, the chain, wire, or cordpasses down through the tube and is provided at its lower end with a ball, by means of which it can be readily drawn downward. The plate is provided with an inwardly-projecting arm Q, which engages the standard and limits the backward movement of the plate. The plate is provided with a slot R and the sheave with a projecting arm or pin S, extending into this slot, and the independent movement of the sheave and the plate is limited by this slot. The upper end of .the standard is provided with a projecting arm a and the plate with a coaeting projecting arm I), so that when the plate through-the medium of the sheave is carried forward it is limited in its movement by the engagement of these arms. The operation of these members is as follows: A downward pull on the chain or cord revolves the sheave and throws its sparking member or arm forward, and as the sheave is connected with the plate through the medium of the spring the plate is carried forward until it is stopped by the engagement of the arm with the I standard or the projection, and a continued pull upon the chain moves the sheave independent of the plate, which has been stopped, thus moving the sparking-awn of the sheave farther forward or farther within the chimney than its coacting sparking member of the plate. The sheave sparking member may be provided at its end with a fine spring, which may be formed of platinum wire, with one or more projecting ends 0. These ends project, and when the sparking-arm of the sheave is moved forward after the plate has been stopped the arms of this spring or the ends of fingers or arm engage the sparking member of the plate, and the further movement of the sparking member of the sheave causes the spring to disengage, and in this way the spark is produced. The backward movement of the parts bring them to the relative position shown in full lines in Fig. 1 ready for a second operation. Passing also through the tubular standard E, when a tube is used, are one or two wires which are connected in the circuit, and one of the wires has itsend projecting, as shown at d, and the sparking memberof the plate has a projecting end 6, so that when the plate is moved forward these two members will engage and make the electrical contact ready for the Y I sparking through the medium of the coacting arm of the sheave and the spring. The other wire is connected with the upper end of the standard in any suitable manner, and as the sheave is electricallyinsulated from the standard the wire is thus electrically connected with the sparking member of the sheave, though this connection may be made in any other desired way. The projectingend of one of the wires which coacts with the projection of the sparking member of the Plate may serve alone as the means for stopping the movement of the plate, though I prefer to use the arms, as before described, which will be more permanent and not so likely to be bent out of position, and thus effect the relative position of the parts of the sparking mechanism.

over or within the upper end of the burnerchimney and that a continued pull moves the sparking member of the sheave farther and causes it or the sparking-spring before described in and out of contact with the sparking member of the plate, thus making and breaking the circuit and causing a spark. By the use of two arms, as here shown, carried by the sparking member of the sheave one or more sparks are produced at each operation of the device, which make the lighting more certain. If the engagement of these spring-arms is light with the coacting sparking member of the plate, then one or' more sparks will be produced by the continued movement of the sparking member of the sheave and one or more sparks made when I the sheave is being released and moves backward independent of the plate by the engagement of these spring-arms with the sparking member of the plate as the cord is being released. In this way one or more sparks are produced when the string is pulled. A device of this character which moves over or within the chimney is especially adapted for the Welsloach and similar incandescent lights. Where these lights are situated at an elevated point, as is usually the case, it is difficult to getat them to light with a match without standing on a chair or other elevated support orto use a taper on the end of a rod. By means of my device it can be attached to the ordinary burner without any change whatever in the burner and is adapted to move within and Without the chimney and cause a spark at the right place for igniting the combined gas and air therein.

I do not limit myself to any detail of construction here shown, for this may be varied without departing from the spirit or scope of my invention, the essential feature of which is the moving of the sparking members over or within the chimney and causing aspark for the purpose of lighting the burner. Many changes and variations whereby this may be accomplished will readily occur to mechanics skilled in this line, and therefore I do not limit myself to the specific construction herein shown for effecting the desired result.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is
